SCAFFOLDING.

SPECIFICATION forming part of Letters Patent No. 391,182. dated Getober16, 1888.

Application filed May 24,1888. Serial No. 274,989.

To aZZ whom it may concern.-

Be it known that I, ORREN G. NOSKER, a citizen of the United States,residing at Sheldon, in the county of Iroquois and State of Illinois,have invented certain new and useful Improvementsin Scaffolding, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention has relation to scaffolding, and the objects andadvantages thereofwill be hereinafter described, and particularlypointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of a scaffoldingconstructed in ac cordance with my invention, the same being set up foruse. Fig. 2 is a bottom plan of the platform-sections. Fig. 3 is an endelevation of the lower portion of one of the platformsection-supportingladders, and Fig. 4 is a perspective of one of the ends of theplatform-sec tions.

Like letters of reference indicate like parts in all the figures of thedrawings.

A A represent the platform-sections, which are laid one upon the other,and may be of any desired length, width, or thickness. The two sectionsare held in sliding contact with each other by means ofoppositely-arranged arms or bails A a pair of which project from thelower one of the sections up over and embrace the upper section, and apair of which also project from the upper section down and under thelower section. The lower one ofthe platform-sections,A,is longitudinallyslotted, as at A said slot terminating short of the ends of thesection.Secured to and depending from the under surface of the upper section,A,into the longitudinal slot A is a staple or eye, A", which, in additionto other .functions hereinafter described, serves as a stop to thelongitudinal sliding of the sections, so as to cause said section touncouple.

At the outer ends of each of the platformsections, and secured to theirunder surfaces, are oppositely-arranged sockct'castings A, which areadapted to receive and rest upon either of the supportingrungs of thetwo oppositely-arranged ladders B B. The height of the platform from theground may be regulated at will by resting the sections thereof uponhigher or lower rungs.

(No model.)

Loosely connected to the staple or eye A* is abrace-rod, A, which isformed with a hooked end adapted to take over one of the rungs of theladder, forming a brace and preventing said ladder from spreading, andalso limits the length or spread of the sections, so that the desiredlength of platform is secured. From an eye or staple, A secured to theunder surface of the lower section, A, there is loosely connected asecond brace'rod, A, having a hooked end adapted to take over one of therungs of the companion ladder at the opposite end of the platform.

Each of the ladders B B is provided with casters or rollers B at itslower ends, so that shifting the scaffolding from one position toanother is facilitated.

One of the sides of each of the ladders B, or it may be each of thesides, if desired, is provided with a series of eyes or staples, Bthrough which is passed and adapted to slide longitudinally a lockingbar or rod, B The lower ends of the rods B are sharpened or beveled ,andare adapted by means of a handle, 13*, formed at the upper end of therod, to be forced down into the ground, and thus render the scaffoldingstable. A kink or laterallyprojecting arm, B is formed upon or securedto the rod B which, when said rod has been forced into the ground, isdesigned to be turned so as to take under a projection, B, projectingfrom the side of the ladder B. By this arrangement the ladder is securedagainst slipping. By turning the rod B so as to disengage its arm B fromthe projection B, and raising said rod until said arm is above saidprojection and then turning the same, the rod will be locked out ofcontact with the ground and the point retained against scraping orotherwise retarding the easy moving of the scaffolding from one point toanother.

Having describing my invention and its operation, what I claim is- 1. Inaseaffolding, the combination, with an extensible platform formed ofoverlapping sections, the outer ends of said sections being providedwith rung-receiving sockets, of supporting-ladders mounted at each endof the platform and diagonal brace-rods connecting said ladders andplatform, substantially as specified.

2. In a scaffolding, and in combination with the platform thereof, endplatform supporting ladders mounted on casters and provided with avertical rod adapted to be forced into the 5 ground, substantially asspecified.

3. In ascaffolding, andin combination with the platform thereof,platformsupporting ladders provided with a locking-rod adapted to beforced into the ground, and means for lock- 10 ing said rod in suchposition, substantially as specified.

4. In a scaffolding, and in combination with the platform thereof,supporting-ladders pr0- vided with a looking-rod adapted to be forced 15into the ground,and provided with alaterallyprojecting arm adapted to bethrown into con- -mounted in the eyes, substantially as-specified. 5

In testimony whereof I affix my signature in presence of two witnesses.
